How Jasper County floods

Flash flooding from severe weather and thunderstorms dominates the historical flood profile of Jasper County, accounting for 47 out of 56 total flood events recorded over the last 30 years, alongside impacts from tropical storms, hurricanes, and tropical depressions.

Recent occurrences documented in the NOAA database illustrate these patterns. A low pressure system brought severe thunderstorms and flash flooding on January 8, 2024, while a band of heavy rain caused additional flash flooding on May 17, 2024. Active weather systems continued to produce flash flooding in early 2025, including events on February 12, February 15, and March 15.

National Flood Insurance Program records indicate that claims have been filed across multiple zones, with the highest claim volume concentrated in Zone A, which recorded 6 claims with an average payout of $19,492 and an average recorded water depth of 1 inch. Zone X recorded 2 claims with an average payout of $31,646 and an average water depth of 1 inch, while unshaded Zone X recorded 3 claims with an average payout of $5,076 and an average water depth of 6 inches. Zone D recorded 1 claim with an average payout of $12,100 and an average water depth of 6 inches. Homeowners and real estate agents managing properties in Zone A and Zone X, as well as unshaded Zone X and Zone D, should pay the closest attention to these flood risks.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.

Flood insurance in Jasper County

If a building in Jasper County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
